cames, l pins w' f which* etd through heres 20, Fig. l, is engaged withthe looper points i by engaging successive loops 21 of the sweaterfabric, along the desired line of reenter-cement, with successive pointsof the looper (see Figs. 2 and The end of the reen'lorcing tape 30,which has been drawn through the tension device t, u, is then engaged byhand with one or more of the looper points that engage the loops at oneend ot the row oi' sweater fabric loops that are hung .troni the looper'points. The wheel m is then swung into the operative pos1tion shown inFig. 2. Rotation of the looper is then started. Those looper pointswhich have pierced the tape 30 operate to pull the tape through thetension device tangentially over the pins "n, of the wheel m. As thelooper' continues to rotate, successive looper lingers engage successivepins n and turn wheel m and at the same time successively pierce tape30. It is also possible to arrange the mechanism so that the looperpoints do not directly engage the pins, but turn the wheelby thelirictional engagement between the tape and the pins. The operationcontinues until there is impaled on the looper points a length of tapeequal to the length oit the row of loops that are engaged with thelooper points; that is, until a strip of reen-forcing tape extendsacross the sweater along the desired entire line of reenter-cement. Thewheel m is then swung out oi' operative relation with the looper.

As the suspended loops of the sweater and the reeni'orcing strip 30 passthe sewing device, the needleyI thereof sews the renforcing tape 30 tosuccessive loops, as shown in Fig. t (a and f Beyond the sewing deviceand between the same and the wheel m, astripper. cam 'lz/ is secured toavbracket a. This cam acts to strip ofi the looper. points successivesweater loops that have been suspended from such points, together' withthe parts of the reenforcing tape attached thereto, until the last loopof the row of loops andthe rear end of the attached reenforcing tape arestripped off the looper, thereby entirely freeing thereenforced sweater.v

Fig. 4t (c) illustrates a row of sweater loops extending at right anglesto the plane of the reenforcing strip 30 and indicates the manner inwhich the reenforcing strip is pernianentl y secured to the sweater;

The looper points are so spaced apart that when the sweater Vis loopedthereon the i'abric is stretched somewhat along the line ol suspendedloops. When, therefore, the sweater is removed from the looper and thefabric along the line of reenforceinent contracts, the reenforcing strip30 is shirre'd or gathered to just the degree desired to enable thefabric vto stretch to the desired degree `along the line ofreenforcement.

Having now 'fully described my invention,

what I claim and desire to protect by Letters Patent is:

l. In a machine for attaching reenforcing strips to knitted garments,the combination with a rotatable looper comprising peripheral pointsadapted to be engaged by a row of loops of. lthe knitted fabric and arotatable wheel adjacent to the periphery of rthe looper and comprisinga circular row of pins adapted to be propelled by the traveling looperpoints and to `be thereby rotated, whereby when a reenforcing fabric visfed tangentially to the wheel, it will be pierced by successive looperpoints as the looper points propel the wheel and will be carried alongby the looper in fixed relation to said row of loops. Y

2. In a machine for attaching reenforcing strips to knitted garments,the combination with a rotatable looper comprising vperipheral pointsadapted to be engaged by a row of loops of the knitted fabric,l arotatable wheel adjacent to the periphery of the looper and comprising acircular row of pins adapted to be propelled by the traveling looperpoints and to be thereby rotated, and a tension device through which areenforcing tape is adaptedl to travel between the looper points andpins and to be pressed by the pins over the looper points asthe looperpoints propel the wheel.

3. In av machine for attaching reenforcing strips to knittedgarments,the combination with a rotatable looper comprising peripheral pointsadapted to be engaged by a row of loops of the knitted fabric, arotatable wheel adjacent to the periphery of the looper and comprising acircular row of pins adapted to be propelled by the traveling looperpeints and to be thereby rotated, the points icing adapted tosuccessively engage and penetrate areenforcing tape'extending betweenthe coacting points and pins, and means at another part of the peripheryof the looper to secure the tape to the row of loops as the-looperrotates. j

4. In a machine for attaching reenforcing strips to knitted garments,the combination with a rotatable looper comprisingperipheral pointsadapted to be engaged by a row of loops ofthe knitted fabric, arotatable wheel adjacent to the periphery of the looper and comprising acircular row 0f pins adapted lto be propelled by the traveling looperpoints and to be thereby rotated, the points being adapted tosuccessively engage and penetrate a reenforcing tape extendingbetweenthe coacting points and pins, means at another point in the lineof travel of the looper points to secure the tape to the row of loops,and a stripper, extending along a part of the periphery of the looperbeyond said securing means, adapted to strip the loops and attachedreenforcing ltape yfrom the looper points.

lili? 5. In a machine for attaching reenforcing strips to knittedgarments, the combina-tion with a rotatable looper comprising peripheralpoints adapt-ed to be engaged by a row of loops of the knitted fabric, arotatable Wheel adjacent to the periphery of the looper and comprising acircular row of pins adapted to be propelled by the traveling looperpoints and to be thereby rotated, and

a lever carrying said Wheel and adapted to 10 be operated to move saidWheel into and out of operative relation with the looper.

In testimony of which invention, I have hereunto set my hand atPhiladelphia, Pennsylvania, on this 4th day of June, 1927.
